It's a lousy redemption system, but I've done it. It sent "sent for fulfillment" for exactly 3 weeks. I got my paper cert on week 3 to the day. (This was just last week.) No one on at UA could answer any questions about the program; I was even stuck reading the "valid routing" T&C on the back of the cert to one CSR. Anyway, once you have cert, you can hold itinerary for 24-hrs. (I was also booking award tkt, so the really great CSR gave me 72-hrs.) Anyway, I didn't have to get the cert to them w/in 24-hours. They just told me to mail it the next day, and I would be fine. This was on Monday, and I assume it's still in the mail since they haven't yet contacted me via email, which they said they would do. All in all, what seemed like a great promotion up front, became a total pain.

If I knew then what I know now, I would have requested the cert the minute I had enough credits (which was months ago). I'm about to request the rest of them for regional domestic, and like previous poster, hand them out to people I want to visit me!

I hope this helps someone.....
